Three women and one man are standing among plants inside a greenhouse in this 5-1/2" x 3-1/4" black and white photograph. There are plants on both sides of an aisle. A watering can and a hose rest on the ground. The man is wearing a collared shirt, a suit, and a tie. The women whose clothes can be seen are wearing long dresses with aprons over them. "In the Greenhouse" is handwritten on the photograph.
